Stefan did an extension for my flat from the installation of structural steel, to the roof, and demolition. To building the shell and all cosmetic work inside. I am very happy with the work. Time keeping was good, pricing was good he was open and honest throughout, he was very tolerant and easy to work with. Always positive and willing to help if there were any issues. He would help resolve any issues in the quickest and best way possible. Very happy. I would happily recommend him.

New Builds- 7 Jun 2022
Sohail worked closely with me on this project. Providing detailed costings, work schedules and build timelines. Filling my knowledge gaps with his extensive experience he was able to assist over and beyond what I expected from him. Unfortunately due to circumstances out of my control this development project didn’t go ahead. However when the next opportunity for a new build comes up I will definitely be using Rose and Stone. I did have another job going at the time where the other builder badly let me down and left me with a big problem on my hands…. Sohail and his team stepped in and took on the project. The team finished the job exceptionally well, which was a full on top to bottom conversion, some internal reconfigurations and with the addition of a loft and new downstairs WC. The workmanship and overall quality of the job was excellent. My wife is over the moon with the results, taking the house from a three bed one bathroom to a four bed 3 bathroom house. We would definitely recommend Rose and Stone for this type of extensive refurbishment/loft conversion work and look forward to working with them in the future on bigger development projects.

Extensions- 24 May 2024
We asked BLG to complete a different job to the one we advertised as weren't ready to start it. Instead they completed a 2 bedroom flat renovation, including ripping out and installation of kitchen, removing plasterboard walls, making good, painting and decorating and recarpeting/tiling. Their work and professionalism was great but even better was their attitude. They were always quick to find good solutions to problems, were extremely accomodating, informative, hard working and prices were very reasonable - at no point did I feel I was being ripped off or being treated like a mug, which after completing multiple renovations in the past am well aware of. I wouldn't hesitate to recommend them.
